Upgrading Ruby using RVM on Digital Ocean's Ruby on Rails on Ubuntu 14.04 (Nginx + Unicorn) Image

For those out there more advanced, this is probably not worth reading. However, if you’re fairly new to system admin on a Digital Ocean Ubuntu/Nginx/Unicorn/MySQL/Ruby on Rails setup, it may help you out. Recently, I needed to upgrade my ruby version from 2.0.0-p353 to version 2.2.0 on my Digital Ocean droplet. I felt like this would be fairly easy to do since RVM comes installed with the ‘Ruby on Rails on 14.04 (Unicorn + Nginx)’ image that Digital Ocean provides under the ‘Applications’ tab when creating a Droplet.

While it is true that installing a new version of ruby using RVM on your system is fairly easy, there’s a few locations that you MUST change in order to use the new ruby version. This is where if you are unfamiliar or new to this, you could spend a decent amount of time digging for these. Hopefully this will save you the time and make your upgrade fairly smooth.

Let’s get started!
